1. A multi-segment device comprising:
an elongate first portion comprising a first metallic material;
an elongate second portion comprising a different metallic material, the first and second elongate portions being directly joined together end to end by a weld;
a heat affected zone surrounding an interface of the elongate first portion and the elongate second portion, wherein the heat affected zone toward a center of the weld has a first thickness across the interface of the weld that is less than a second thickness across the interface of the weld at a location towards a perimeter of the weld;
a shapeable distal end formed from at least a portion of the elongate second portion; and
a coil disposed about a portion of the elongate second portion.
